Figure 5.47 Selecting P-Level
4.
The catheter operation icon in the lower left corner of the screen begins rotating when
the Impella
®
LD Catheter begins to operate.
5.
Increase P-level to P-9 to confirm correct and stable placement. Verify placement with
TEE and the placement screen (see Figure 5.48). Reposition the catheter as necessary.
Check Positioning
at Maximum Flow
When the flow rate is
increased to maximum flow,
the Impella
® LD Catheter
has a tendency to be drawn
into the ventricle. Check
positioning at maximum flow
to ensure proper placement
throughout the P-level setting
range.
Addition of Heparin to
the Purge Solution
As soon as practical after
placement, change the purge
fluid to include heparin.
The recommended heparin
concentration is 50 IU/mL
in 20% dextrose solution.
(Follow the Change Purge
Fluid procedure described
later in this section to change
the purge fluid.)
